SELF-LOCKING WIRELESS MOLDED ROOFING.

Application led March 81, 1921. Serial No. 457,564.

To aZZwwm 'it may concern.'

Be it known that I', FRED OrnNsHAW a subject of the King of GreatBritain, and a resident of Gonville, Wanganui, New Zealand, haveinvented a new and useful Self-Locking Wireless Molded Roofing, of whichthe following is a specification.

The object of my invention is to provide an improved interlockingroofing construction which can be readily fitted together on the roof,and which, when in place, will provide a water-proof roof, free fromvprojections that would cause water to collect underneath and drip. Itis further an object of my invention to provide a molded roofing havingnovel means for interlocking the various tiles or slabs and securingsame at the ridge of the roof, at the eaves, and to successive battensand to adjacent tiles. It is a further ob'ect of my invention to providea form o roofn adapted for use on roofs of irregular s ape, havinggables, hips, and eaves locks. It is `further my object to provide anovel combination arrangement of parts shown and descrlbed; and tolprovide a roofing which does not require the use of mortar. I attainthese and other objects of my invention by the structure illustrated inthe accompanying drawings, or modifications thereof.

Figure 1 is a top plan of the main block or tile 1;

Fig. 2 is an end elevation of the left hand end of one of the tiles;

Fig. 3 is an end elevation of the right hand end of one of the tiles;

Fig. 4 is a section on line 4--4 transversely through the tile;

Fig. 5 is a section on line 5-5 of Fig. 1, longitudinally of the tile;

Fig. 6 is a section on line 6-6 of Fig. 1;

Fig. 7 is a vertical section through the roofing with the 'tiles inposition;

Fig. 8 is a section on line 8--8 of Fig. 7, illustrating how the tilesinterlock;

ig. 11 1s a detail section of an improved form of beveled batten forlocking the tile in place at the top;

Fig. 12 is a similar detail sectional view of an equivalent metal battenand Fig. 13 is a detail sectional view showing `groove 29.

to cut the top course. End arch 9 is Like numerals designate likeyReferring to the accompanying drawings i I provide a'tile or block 1shaped to interlock with similar successive tiles. At the 'apex of theroof l provide duplicate reversely disposed scribers or horizontal ridgelocklng strlps 3 mounted on the uppermost tiles'l, and in turn'supporting the cap piece or ridge tlle 2. Tiles 1 are each providedwith an upper hook end 16 which engages over suitable battens 4. Mountedon the bottom batten I provide a suitable horizontal filler strip 5.

Referring to Figs. 1 and 2, tile`1 is providedwith a central tile arch 6having a longitudlnal top rib 8, and having a longitudinal socket 7 atone end of the arched portion. Tile 1 is also provided with an end arch9, said end arch 9 having a cut-out portlon 30 where the lower part ofsocket 7 is slid under the lip 14 and locks the toe or bottom end of thetile to the lip at the top end of the tile under which it laps, andholds just the same even when the tiles are telescoped more than usual,in order to sult the length of rafters, instead of having rovided on itsunder side with the longitudlnal grooves 10, as shown in Fig.' 2, whichgrooves interlock with the corresponding ribs 11 of the adjacent tile,as shown in Fig. 8. On the other end of the tile from that provided witharch 9, I provide the under curved surface 12 and the longitudinal undergroove 13. The longitudinal end or tip 14 of end arch 9 is provided toseat in socket. 7 of the tile above, as shown in Fig. 8.

Referring to Fi 2, I provide edge lugs 15 on the'left han end of thetile 1, which fill the spaces between arch 6 and arch 9 and the spacebetween the succeeding arch 6 and ribs 11, as shown in Fig. 8.. I'further provide edge lugs 16 on the right hand of tile 1, as shown inFig. 3 and Fig. 4. Edge lugs 16 may be provided with suitable nail holes1 7, as shown in Fig. 5, or said nail holes may be omitted. and the hookshape of said lugs be depended on for locking them in place. As shown inFigs. 5 and 6, I provide the angular notch 18 for hooking the tiles overa beveled batten 19, or over an equivalent metal batten 20, as shown inFigs 11 and 12, respectively.

Referring to Fig. 9, the filler block 5 may be provided with `nailholes` 24 and with suitable arched or recessed ortions 21 and 22 to seatin the correspon ing recesses of the bottom row of tiles 1. l

Referring to Figs. 7 and 10, the members 3 are provided with. hook ends27 which engage over the upper lateral edge of the top row of tiles 1;and also with the longitudinal ribs 25 which seat in the corres endinglongitudinal recessed bottom portions 26 of the cap pieces or ridgetiles 2. The said members 2 are provided with an end rib 29 and with acorresponding end socket 28 to abut against the rib 29 of the contiguouscap piece or ridge tile 2. The partially cylindrical longitudinal ribs25 have an important new and useful function in permitting of theridge-locking strip 3 adjusting itself automatically to varying pitchesof roofs without interference with its function as a locking member.

In operation the successive tiles are engagedone over the other in themanner illustrated in the drawings, with the recessed portions of theuppermost tiles engaging over the corresponding ribs and ridged portionsof the layer of tile immediately underneath. At the top of the roof thehook portions 27 of the scribers engage over the upper edge of thetopmost layer of tiles and the cap and the ridge tiles in turn engageover the longitudinal ribs of the aforesaid scribers. The hooked ends ofthe successive layers of tiles similarly hook over the respectivebattens, and may or may not be nailed to said battens, it being withinthe contemplation of my invention to use either Wooden or metal battensof any suitable shape.

It is also Within the contemplation of my invention to cut the tilestoany suitable shape for gable roofs and roofs of irregular shape andconstruction and provide suitable scrivers to fill in the spaces causedin litting the tiles to the irregular shaped type of roofs.

Itis within the contemplation of my invention to provide an eaves trough31 secured between the horizontal tile strip and the lowermost batten 4by nails 24, as shown in Fig. 7.

What I claim is:

1. In a self-locking molded roofing, the combination of successivelayers of recessed and ribbed interlocking tiles, each layer of saidtiles having hooked end strip portions, battens extending longitudinallyof the roof and on which the hooked ends of the tiles engage, horizontalridge locking strips eX- tending longitudinally of the uppermost layerof tiles, said horizontal ridge locking strips having hooked lateralstrip portions engaging over the upper lateral edges of the top layer oftiles, said portions also having outwardly projecting longitudinal ribs,and ridge tiles having correspondingly recessed inner edge portionsadapted to engage on and interlock with the ribportions of the aforesaidlocking strips substantially as set forth.

2. As a new article of manufacture, an interlocking molded tile forrooting, c011- sisting of a main tile body having an end archedportionsaid end arch being provided with longitudinal grooves on itsunder side, the tile also having a central longitudinal arched portion,said portion having a longitudinal external rib, and the tile havinglongitudinal ribs and a longitudinal recess at the end farthest from thefirstnanied end arch, and lugs on one side of the tile, said lugs beinghook shaped.

3. In a molded tile rooting, the combination of a series of rows ofinterlocking tiles, each of said tiles having a hooked upper edgeportion, battens extending horizontally of the roof on which said tilesare hooked and nailed, purlins of hook shape engaging over the lateraledge of the uppermost row of tiles, ridge tiles shaped to interlock onthe aforesaid purlins and over-lap the op )osite uppermost rows of maintiles, and filler pieces secured to the lowermost battens and over whichthe lowermost row of tiles are hooked.

4. In a roofing of the class described, the combination of a ridge tilehaving longitudinal grooves, horizontal locking strips having outwardlyprojecting curved ribs engaging in the grooves of the aforesaid ridgetiles and roofing tiles on which the horizontal locking strips arehooked, and said horizontal locking strips and said tile members havingoppositely projecting ribs engageable one over the other substantiallyas shown.

5. As a new article of manufacture in a roofing of the class described,a ridge-lock ing strip having a hooked edge portion adapted to engageover the lateral edge of the top row of tiles 0f the roofing, and alongitudinal rib on the exterior of said ridge-locking strip, said ribbeing semi-circular in cross section and adaptedto adjustably interlockwith a correspondingly shaped recessed socket of a ridge tile, wherebythe different or varying pitch.
